NAME

    Blockchain::Ethereum::Keystore - Ethereum wallet management utilities

VERSION

    version 0.009

SYNOPSIS

    Generating a new address and writing it to a keyfile:

        my $key = Blockchain::Ethereum::Keystore::Key->new;
        # checksummed address
        print $key->address;
        my $keyfile = Blockchain::ethereum::Keystore::Keyfile->new;
    
        $keyfile->import_key($key);
        $keyfile->write_to_file("...");
        ...

    Generating a new seed and derivating new keys (BIP44):

        my $seed = Blockchain::Ethereum::Keystore::Seed->new;
        my $key = $seed->derive_key(0);
        print $key->address;
        ...

    Importing a keyfile and changing the password:

        my $keyfile = Blockchain::Ethereum::Keystore::Keyfile->new;
        my $password = "old_password";
        $keyfile->import_file("...", $password);
        $keyfile->change_password($password, "new_password");
        $keyfile->write_to_file("...");

    Signing a transaction:

        my $transaction = Blockchain::Ethereum::Transaction::EIP1559->new(
            ...
        );
    
        my $keyfile = Blockchain::Ethereum::Keystore::Keyfile->new;
        $keyfile->import_file("...");
        $keyfile->private_key->sign_transaction($transaction);

    Export private key:

        my $keyfile = Blockchain::Ethereum::Keystore::Keyfile->new;
        $keyfile->import_file("...");
    
        # private key bytes
        print $keyfile->private_key->export;

OVERVIEW

    This module provides a collection of Ethereum wallet management
    utilities.

    Core functionalities:

      * Manage Ethereum keyfiles, facilitating import, export, and password
      change.

      * Sign Blockchain::Ethereum::Transaction transactions.

      * Private key and seed generation through Crypt::PRNG

      * Support for BIP44 for hierarchical deterministic wallets and key
      derivation.
